Pot’s Addictive – Just Add Tobacco | www.dailyrx.com


Marijuana is the most commonly abused drug in the United States, and while most do not become dependent, a new study suggests adding tobacco to cannabis smoking makes it easier.

Researchers from the psychiatry department at the Yale University School of Medicine discovered that blending marijuana with tobacco increases dependence on the drug as well as its mind-altering effects.

“Cannabis users who also smoke tobacco are more dependent on cannabis, have more psychosocial problems, and have poorer cessation outcomes than those who use cannabis but not tobacco,” writes lead author Erica Peters, Ph.D., and colleagues.

“The converse does not appear to be the case.”

According to research findings, cigarette smokers and other tobacco users did not seem to use tobacco more often or have a harder time quitting when smoking a mix.

These discoveries were made through a systematic review of twenty-eight studies into the co-occurring usage of both substances. Sixteen of the studies investigated clinical diagnoses, such as cannabis use and tobacco use disorders, four examined psychosocial problems, while eleven recorded cessation outcomes.

The experiments typically compared blended substance use against a single-substance, either marijuana or tobacco.  

One review included a cross-sectional study of 481 U.S. marijuana users, and authors write, “Cannabis-tobacco use in the form of ‘blunts’ and ‘chasing’ cannabis with tobacco was associated with five symptoms of current cannabis dependence, while cannabis use [alone] in the form of ‘joints’ or ‘pipes’ was associated with only one symptom.”

These findings suggest the addition of tobacco to a marijuana "joint" causes the body to react significantly more to the combination of substances than it would to smoking it alone.  

Although only a small percentage of people typically become dependent on marijuana, making a habit of combining its use with tobacco will increase will increase the likelihood of addiction.  

Cannabis dependence is characterized by withdrawal from the substance, affecting sleep, appetite, concentration, mood, and perspiration. If you or a loved one is suffering, talk to a medical health professional.

The journal Addiction published this study on February 16, 2012, and the National Institute on Drug Abuse provided funding. Dr. Peters and colleague Kathleen Carroll report no conflicts of interest, while co-author Alan Budney, Ph.D., reports past consulting with G.W. Pharmaceuticals.

Marijuana Use

The 2009 National Survey on Drug Use and Health reported that 16.7 million Americans aged 12 or older used marijuana at least once in the month prior to being surveyed, and it is the most used illegal drug in the United States. It is cultivated from the buds and flowers of the plant Cannabis sativa, and is most commonly smoked as a cigarette or in a pipe to achieve the short-term psychoactive effects of euphoria, altered consciousness, and many others.

Short term physiological effects include increased heart-rate, dry mouth, red eyes, and muscle relaxation. Negatively, marijuana use can cause distorted perceptions, impaired coordination, difficulty with thinking and problem solving, and problems with learning and memory.
